Answer:
The length of the base is 
Step-by-step explanation:
Since we know the formula to find the area of a triangle is 
, we can plug in and solve for b. When we plug into the formula we get:
= 
First multiply by 2 on both sides to get rid of the 1/2 on the left. After doing this we get:
Then we can multiply by 5 on both sides to get rid of the 1/5 on the left. After doing this we get out answer:
Answer:
I only have an answer to number 2 but the dimensions are 20 and 120.
Step-by-step explanation:
well you can remove the zeroes and factor either the 28 or 24. (I think 24 is the best) so when you factor it you get 2 and 12 because 2 x 12 is 24 and 2 + 2 + 12 + 12 is 28. Then add the zeroes and you have your dimensions. I hope that explanation helped with number 2.
Answer:
a = 2
Step-by-step explanation:
If M is the midpoint, 1/2 of FG = FM since FG is the whole length.
FG = 14a + 1
1/2 FG = 1/2(14a + 1)
1/2 FG = 7a + 1/2
The length of the segment FM = 14.5 and that is the same length as 1/2 FG
7a + 1/2 = 14.5
1/2 = 0.5
7a + 0.5 = 14.5 Subtract 0.5 from both sides
7a = 14.5 - 0.5
7a = 14 Divide by 7
a = 14/7
a = 2
Answer:
Point a is (-1/2,-1/4)
